Battery (Sharp EA-BL06) - $30: 6 months old, used a couple of times to make sure it works fine, it was supposed to be a backup battery but I don't think I'll ever need it...
Serial Cable (Sharp CE-170TS) $25: 6 months old, NEVER used. I have a 5000D and I figured I'd best invest in a wireless compact flash card, which I did

Shipping:
I'll only ship within the US and "I'll pay for the shipping". I have the original packaging for both.
